Comment: ex. Miguel Romero, A most unusual matrix of snow-white, botryoidal calcite, with spheres up to 5.0 cm across, is the host for discrete, glassy and gemmy, lavender, fluorite crystals, to 2.5 cm across. Every fluorite crystal exhibits incredibly complex and dramatic stepped growth. The color contrast is also marvelous. I have not before seen fluorite of this particular style ON this kind of matrix from here, and the Romero collection had just one large piece , from which we trimmed away a damaged portion to create this far better , if smaller, specimen - still a full cabinet size, but now without the damage he would have seen on a portion of the original piece. Comes with custom lucite base already made for the specimen. This specimen was on loaned exhibit in the University of Arizona Museum for over a decade until my purchase of this collection in 2008.
